Im confused. How did Adlet run out of the fortress with flamie after the barrier was activated?

I just started this show and Im enjoying it but one thing has been eating away at me. Since they got into the temple and the barrier was already activated with them all inside they were freaking out like they were stuck in there, but then when Adler is suspected he grabs Flamie and runs out of the temple with her like it was nothing. Did I miss something or did the barrier just cover the area surrounding the temple?
